CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 337,847, dated March 16,1886.

Application filed November 14, 1885. Serial No. 182,867. (No model.)

To aZZ whom it may concern.-

Be it known that I,J0HN CHARLES FREMONT MoOAULEY, a citizen of the United States, residing at Crooked Creek, in the county of Ford and State of Kansas, have invented a new and useful Improvementin Oar-Couplings, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improvement in carcouplings; and it consists in the peculiar construction and combination of parts, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is aperspectivc view of a car-coupling embodying my invention. Fig. 2 is a horizontal secelevation. Fig. 4 is a similar View of the opposite side. Fig. 5 is a detail perspective view, partly in section, of the uncoupling device.

A represents a drawhead, which is applied to the ear in the usual way, the said draw-head having a central opening, B, in its front side to receive the ordinary coupling-link, the top and bottom portions of said opening having the aligned vertical openings 0, through which passes the ordinary coupling-pin. From one side of the draw-head project horizontal ears D, through which are made aligned vertical openings b, to receive a pivotal bolt, E. On the opposite side of the draw-head from the lugs D is a box or frame, F, which is opened on its front and rear sides, the inner face of said opening being inclined, as atf. In the outer side of this box or frame is j ournaled a vertical hinged jaw, G, having upwardly and downwardly projecting spindles that pass through openings made in the upper and lower sides of the box or frame to receive them. An arm, 9, is attached to the lower end of the lower spindle, and on said spindle is placed a coiled spring, 9, one end of which is attached to the arm and the other end bears against the recess in the box or frame, to keep the said jaw normally in the position shown in solid lines, in Fig. 2. The jaw G moves through nearly the fourth ofa circle, its movement being limited in one direction by the outer side of the box or frame F, and its inward movement being limited by a stop, f.

In between the lugs D, on the bolt E, is piv- Fig. Sis a detail side oted a draw-hook, H, and on the same bolt is secured one end of a plate, I, which bears on the upper rear side of the draw-hook. The said hook has a recess, h, on its inner end, and at right angles to this recess is a second recess, h. A projection, 15, extends from the lower side of the plate I and enters either of said recesses, so as to secure the draw-hook either in the position shown in solid lines in Fig. 2, or in dotted lines in the said figure. The lower stud D has a rearward extension, D, in which is cut a vertical slot, D". A rod, K, passes through the slot and is secured in an opening made in the inner end of the plate I, and to the lower end of this rod is attached a weight, k, the function of which is to keep 7 the plate I depressed against the inner end of the draw-hook, so as to maintain the said hook in either position heretofore described.

On the under side of the car, and to the under side of the guideways in which the drawhead is secured, are journaled hollow cylindrical rock-shafts L, which are provided with heads L at their meeting ends, the said heads being coupled loosely together. To the outer ends of these rock-shafts are secured heads L", which are provided with projecting arms L, that extend at right angles to the rock-shafts, and in the outer ends of said heads are fulcrumedlevers M,to theinnerends ofwhich are attached rods M', that extend through the hollow rcckshafts. By moving the outer ends of these levers in and out the rods M will be caused to move longitudinally in the rockshafts.

The central bearing, 0, in which the inner end of one of the rock-shafts is journaled, is provided with a depending projection, O,having a pivotal horizontal bar, 0, extending from its inner side. On this bar is pivoted a pawl or detent, T, which is adapted to engage with a notch, Z, thatis cut in one of the circular heads of the'rock-shaft, so as to secure the latterin the position shown in solid lines in Fig. 6. The inner ends of the rods M are connected to the detent by means of links M WVhen either of the rods is moved outwardly, its link tightens or pulls upon the detent, so as to cause the latter to engage with the notch Z, when the rock-shafts are partly rotated, which may be done by grasping either of the levers M, one of which is on each side of the car. An arm, Z, projects upwardly from the inner end of one of the rock-shafts, and this arm is connected to the arm which controls the jaw G by means of a rod, Z In this rod is included an extensile spring, 1 the function of which is to keep the rod tight at all times. On the end of the car, at the upper side thereof, are secured two vertically-movable rods, S andS. The rod Sis attached directly to the arm L3 by a cord or chain, 8. On the end of said arm is journaled a bellcrank lever, 'I", one arm of which is connected to one of the fulcrumed levers M, the other arm being connected to the rod S by means of a cord or chain, 8. The draw-hook of another car provided with myimproved coupling enters the opening in the box or frame F, and engages with the spring-actuated jaw G,when the cars come together,and thereby automatically couples the cars. By pulling upon the rod S, or by moving either of the levers M to rotate the rock-shafts, thejaw G will be withdrawn so as to reach the draw-hook, and thereby uncouple the cars. When it is desired to permit two cars to come together without coupling, the jaw G will be first caused to swing rearwardly, and by pulling upon the rod S one of the rodsll I will be moved outwardly to cause the detent to eugage with the rock-shafts and lock the said shafts, and thereby fasten or secure the jaw G in that position.

A car provided with my improved couplings may be connected to another car by means of the ordinary pin-and-link couplings in common use.

It will be observed that the opening in the box or frameF extends vertically for some distance above and below the draw-head, and that the jaw G is of a length corresponding to the said opening. By this construction it will be readily understood that cars of unequal heights provided with my improved couplings may be readily coupled together.

Having thus described my invention, I claim 1. The combination of the draw-head, the pivoted draw-hook, having the recesses h and h, and the weighted plate I, having the projection for engaging with said recesses for the v purpose set forth, substantially as described.

2. The combination, in a car-coupling, of the spring-actuated coupling-jaw G, the rockshafts connected to said jaw for moving the same, and the detent for locking the rockshafts to prevent rotation thereof, and thereby secure the jaw G against movement, and the levers M, connected to the said detent, substantially as described.

3. The combination, in a car-coupling, of the spring-actuated couplingjaw G, the rockshaft connected to said jaw for moving the latter, the detent for engaging with the rockshafts, the lever connected with the detent, and the fulcrunied bell-crank lever connected to the said lever, and the movable rod S, connected to the bell-crank lever, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses. I

JOHN CHARLES FREMONT MOCAULEY.
